  "details" : [ "Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running containers do not need to be restarted.", "A file permissions vulnerability was found in Moby (Docker Engine). Copying files by using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host's filesystem, which might lead to permissions escalation and allow an attacker access to restricted data." ],
